For a a variety of reasons, I am opting to install an electric vs. engine driven compressor on my truck to power the exhaust brake and other air accessories which I will be installing. I am looking for user experiences, either positive or negative, with either the extremeoutback magnum or the Viair 550C series compressors. Also open to other suggestions, but these are the ones I am leaning towards due to their 100% duty cycles at 100 psi. Thanks for the input.
